They do not show the same season. one is faced a different part of the sun
N=n×Nav
n=N / Nav
(5.71×10^22) / (6.02×10^23)
n=0.09mol
Answer:
See attached picture.
Explanation:
Hello!
In this case, by considering that the carbon has four valence electrons as it is in group IVA, sulfur has six valence electrons as it is in group VIA and bromine has seven valence electrons as it is in group VIIA we infer that the carbon is the central atom in CSBr2 so one double bond between carbon and sulfur makes it complete the octet and two carbon-to-bromine bonds are formed in order to complete the octets of both carbon and bromine as shown on the attached picture.
Best regards!
